PORTABLE VAPOR-BURNER INCANDESCENT LAMP.

Application filed. January 2, 1924. Serial No. 684,067.

To all whom it may concern:

Be it known that I, MALCOLM MACFAR- LANE, a subject of the King of Great Britain, residing at 151 Farringdon Road, London, E. C. 1, England, have invented certain new and useful Improvements in or Relating to Portable Vapor-Burner Incandescent Lamps, of which the following is a specification.

This invention has reference to portable vapor-burner lamps of the kind provided with a body or reservoir for holding paraflin or petroleum under pressure and adapted to produce their own vapor for use with an incandescent mantle or mantles.

The main object of. the present invention is to provide a convenient arrangement of such a lamp, which can be used in various positions to give a light either upward or downward without any appreciable difficulty from the shadow of the body or the parts around the burner For instance whether it be placed on the floor or be hung from the ceiling or from a hook against the wall the lamp will in all cases throw a useful light clear of the body or reservoir.

Such a lamp is very suitable for almost all purposes for which either ordinary or binnacle' lamps are used, but besides giving a superior light, its useful beam or light zone is not broken. up or obstructed by shadows especially from the lamp body or reservoir to any appreciable extent.

According to the invention, the lamp head or burner-proper (comprising the usual vapourizer device, hood or chimney, and the inverted mantle, globe, etc.) is arranged at one side of the lamp body or reservoir which latter is preferably of flat or squat shape and has a suitable handle whereby it can be either suspended from a chain or cord, or hung on a hook or nail against a wall. The said lamp head and body may be approximately on a level and be connected by a short oil tube of the usual kind, so that they are close together thus'giving a very compact and neat-looking construction.

The arrangement is such however that when the body is in the normal position, that is to say with its base horizontal, the burner is inclined or tilted at a decided angle, its axis being for instance at about 1 5 ins a e ei svetisal a n ordin ry arrangements. In this way the inverted mantle is tilted outwardly, and thus throws an effective beam upward past the outer be side-by-side with the body in a tilted or sloping position, with the globe in its lower partoutward or further from the body.

In this position it will for example throw its light in an upward direction from a point near the floor level which is very convenient in garages for instance when working underneath a car.

When however the lamp is used as a" walllamp and hung on a hook or nail, the lamp head or burner may be exactly vertical, the body being then next the wall but on a slope. This is provided for by suitably sloping the handle or bracket of the lamp, a slot being provided. therein in the usual way for a hook or naihhead to engage in. In this position the lamp gives light downwards and sideways and the arrangement may be such that the lower edge of the lamp body is practically clear of the light cone given out from the inverted mantle.

'On the other hand the handle or bracket may have a loop or eye for hanging it from a chain or cord, in which case the body or reservoir may be more steeply inclined,

the heador globe consequently being tilted. somewhat inward towards or slightly un derne-ath it, and being inclined the opposite way to its ordinary inclination. The bottom edge of the said body will then be level with or above the top part of the mantle, and the lamp will givea clear. and unobstructed light both sideways and downward.

Hence the lamp can be used in its din q' 2ft ferent positions to give a practically clear and shadowless or uninterrupted illumination either upward, sideways or downward,

as desired. a

The lamp-body or reservoir which as stated is preferably of squat shape, may in v fact. be somewhat like a small gas kettle and similarly may have" a horizontal handle above it to facilitate carrying. The stem or Wire which carries thishandle may have a .bend or loop, such .asfabove referred. to

for the ready attachment of a chain or" other suspender, .and its end may be secured 1;, ina ,plategst-rip or bracket piece attached to. the lamp-body or to the rear edge of its base. This plate or bracket may have a of. burner-head, so that when it is hung a will be vertical.

'In order that the invention may be. clearly Y understood and're'adily carried into eliect reference Will-now belied by Way of example to :the. accompanying diagrammatic drawings, iai'whicli: y Y

The hollow arm or tube It may contain the usual filter and is provided with ribs or the like as shown to keep it cool. One end is connected to the casing'of the burner head I) by a-union coupling, whilst the other end is provided with a square block or head 72, which is seated in a square bend i in an upright fiat strip. or bracket i of iron soldered to the-body a and extending up to I the end of the handle: 0..

The small oil-tube g, is looped as shown to give it flexibility and passes through. the

bracket it into the end of the tubular arm h,

the whole made firm andseeure by a fixing nnt .z'

At the rear ofthe-lamp, viz,.the-sideoppositethe burner-head. b is another bracket 70 formed by a. wide fiat plate. arranged at an incline parallel with the burner head. This bracket is provided with a key hole slot ,or'thelike [0' so that the-lamp can be hung up byit on a nail or hook as in Fig. 3 against a wall for instance,andv will remain steady on-account of the widthof the bracket, with the burner head practically vertical.

The handle 0 is of wood: or other. noncond-ucting material andiscanried by a stout wire or bent rod Zsecured atits end to? the twoabrackets- 0', k. This wire or -rrz el 2is prof videdi with a bent portion or loop Z by whichit can be hung. from a chain or other suspender. Z as in 4;; The,;.said. loop. is situated at one end of the handle,. so that when the lamp is suspended-the body a is tilted up out of the way, and the light from the mantle b can pass freely sideways and downwards Without interference.

It will be readily seen that such a lamp has. many usesespecially' for teehnieal,-- industrial or outdoor purposes. For instance as already explained it will serve to. irl lmninateefficiently the underneath pnrtions' of a motor chassis by throwing anrupwandly slanting beam when placed the Fig. 1' position) "directly on the floor, thius greatly facilitatingrepair work.v .lntheisame position it canbe placedzon the edge of a table or on a shelf or bracket with the burnerhead' and mantle pnoj-ecting. over the edge andso givinga light underneath. positions shown, in Figs- 3 and- 4= explain themselves after-what has-beensaid; above,

the burner-.head heingvertifial in the-tovnrer,

Whilst in the latter it is inclined the opposite Way to Fig. 1. It may also be mentioned that the lamp is quite unspillable.

Obviously the above arrangements may be modified in various Ways in carrying the invention into effect Without departing from the general nature thereof.

I claim 2- 1. In a portable oil-vapor burner lamp,

the combination of an oil reservoir, a burner head at one side thereof normally inclined in one direction, means for supporting the lamp so that said burner head is vertical,

and means for suspending it so that the burner head is inclined in the other direction substantially as described.

2. In a portable vapor-burner lamp, the combination ofan oil-reservoir, an inclined burner head at one side thereof, and an inclined bracket at the opposite side, substantially as described.

3. In a portable vapor-burner lamp, the combination of a flat-bottomed oil reservoir, a sloping burner head at one side thereof, a sloping bracket at the opposite side thereof, and a Suspender loop arranged above the oil reservoir, substantially as described.

4:- In a portable oil-vapor burner lamp, the combination of an oil reservoir, an inclined burner head, a tubular connector-arm having heat-radiating ribs, and a handle to Which said connector-arm is secured, sub stantially as described.

In testimony whereof I affix my signature.
